Answer:
6n + 3 = 4 + n
Step-by-step explanation:
Answer:
6n-3=4+n
Step-by-step explanation:
Ok since it is saying "the product of six and a number" it is a multiplication of the two variables 6 and n, which will give you "6n." The next part is "three less than." This is a subtraction cause you are subtracting 3 from 6n. The last part "the sum of four and n." Is an addition because it has the word sum, which will give you 4+n.
Product=multiplication
Less than=subtraction
Sum of= Addition

Evaluate the function for x = 2,3,4
F(x) =2x-7-3
Answer:
below in bold
Step-by-step explanation:
f(x) = 2x - 7 - 3
~Combine like terms
f(x) = 2x - 10
When x = 2...
f(x) = 2(2) - 10
f(x) = 4 - 10
f(x) = -6
When x = 3...
f(x) = 2(3) - 10
f(x) = 6 - 10
f(x) = -4
When x = 4...
f(x) = 2(4) - 10
f(x) = 8 - 10
f(x) = -2

A bin at a department store contains blue and red blankets. The ratio of blue blankets to red blankets is 13 to 7. What percent of the blankets in the bin are blue?
Step-by-step explanation:
13=blue blankets 7=red blankets
First, we need to know how many blankets there are in total.
13+7=20
Now, we don't need the seven anymore. Our ratio is blue blankets to total blankets.
13/20
Now, we need to know how many blue blankets there are in percentage.
13/20 = x/100
Next step: 13 times 100 is divided by 20
x= 13(100)÷20
x=1300÷20
x= 65
Therefore there are 65% of blue blankets.

solve for y
Answer: [tex]y=\frac{-x}{w-3}[/tex]
Step-by-step explanation:
To solve for y, we want to isolate y.
[tex]w=\frac{3y-x}{y}[/tex] [multiply both sides by y]
[tex]yw=3y-x[/tex] [subtract both sides by 3y]
[tex]yw-3y=-x[/tex] [factor out y]
[tex]y(w-3)=-x[/tex] [divide both sides by (w-3)]
[tex]y=\frac{-x}{w-3}[/tex]
Now, we know that [tex]y=\frac{-x}{w-3}[/tex].
The probability of two events A and B happening simultaneously is 0.17. The probability of only event A happening is 0.34. Find the probability of event B happening, if event A has already happened
Answer:
because is the probability is 0.17 and 0.34 is fair
You can use the multiplication rule of probability.
The probability of event B happening if event A has already happened is 0.5
What does general multiplication rule of probability says for 2 events A and B?[tex]P( A \: \rm and \: B) = P(A)P(B|A) = P(B)P(A|B)[/tex]
Since we've to find the probability of B given that A has already happened, we need [tex]P(B|A)[/tex]
Since the probability of both event A and event B happening simultaneously is 0.17, thus:
[tex]P(A \: \rm and \: B) = 0.17\\
[/tex]
Since the probability of only event A happening is 0.34, thus:
[tex]P(A) = 0.34[/tex]
Thus, from the multiplication rule, we have:
[tex]P(A \: \rm and \: B) = P(A)P(B|A)\\
0.17 = 0.34 \times P(B|A)\\\\
\dfrac{0.17}{0.34} = P(B|A)\\\\
P(B|A) = \dfrac{1}{2} = 0.5[/tex]
Thus, we have the probability of event B happening when A has already happened as 0.5

What is the first step needed to solve 4 over 7 multiplied by x minus 5 equals negative 13? Subtract 13 from both sides Divide both sides by 7 Add 5 to both sides Multiply both sides by 4
Answer: C) add 5 to both sides
The given equation is
(4/7)x - 5 = -13
To solve this, we follow PEMDAS in reverse undoing each operation. Normally parenthesis is the first thing we look for, but instead we start with subtraction.
So we'll undo subtraction which means we add 5 to both sides

Find the slope and y-intercept from the following graph of a linear equation.
Answer:
A
Step-by-step explanation:
The equation of line is y= -4x -23
What is slope- intercept form?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively.
The slope of the line is the ratio of the rise to the run, or the rise divided by the run, therefore the change in y coordinate with regard to the change in x coordinate may be expressed as follows. In the coordinate plane, it describes the slope of the line.
Given:
We can take the coordinates from the given graph as (0, 3) and (2, -5)
Now, the slope = (-5 - 3)/ (2 - 0)
slope= -8/ 2
slope= -4
Now, using the point- slope form
(y - [tex]y_1[/tex]) = m(x - [tex]x_1[/tex])
(y- (-3))= -4( x- (-5))
y+3 = -4(x+5)
y+ 3= -4x - 20
y= -4x -23
Hence, the equation of line is y= -4x -23.

In triangle RST, m∠T is 5° more than m∠R, and m∠S is 10° less than m∠T. What is the measure of each angle?
Answer:
R=60
S=55
T=65
Step-by-step explanation:
[tex]\boldsymbol{m\angle R, m\angle S, m\angle T}[/tex] are equal to [tex]\boldsymbol{60^{\circ},55^{\circ},65^{\circ}}[/tex] respectively.
According to angle sum property of a triangle, sum of all angles of a triangle is equal to [tex]\boldsymbol{180^{\circ}}[/tex]
Let [tex]m\angle R=x[/tex]
As [tex]m\angle T[/tex] is [tex]5^{\circ}[/tex] more than [tex]m\angle R[/tex],
[tex]m\angle T=5^{\circ}+m\angle R[/tex]
[tex]\boldsymbol{m\angle R=m\angle T-5^{\circ}}[/tex]
Also,
[tex]m\angle S[/tex] is [tex]10^{\circ}[/tex] less than [tex]m\angle T[/tex],
[tex]\boldsymbol{m\angle S=m\angle T-10^{\circ}}[/tex]
So,
[tex]\boldsymbol{m\angle R+m\angle S+m\angle T=180^{\circ}}[/tex]
[tex]m\angle T-5^{\circ}+m\angle T-10^{\circ}+m\angle T=180^{\circ}[/tex]
[tex]3m\angle T-5^{\circ}-10^{\circ}=180^{\circ}[/tex]
[tex]m\angle T=\frac{195^{\circ}}{3}[/tex]
[tex]\boldsymbol{=65^{\circ}}[/tex]
[tex]m\angle R=65^{\circ}-5^{\circ}[/tex]
[tex]\boldsymbol{=60^{\circ}}[/tex]
[tex]m\angle S=65^{\circ}-10^{\circ}[/tex]
[tex]\boldsymbol{=55^{\circ}}[/tex]

A poll agency reports that 45% of teenagers aged 12-17 own smartphones. A random sample of 152 teenagers is drawn. Round your answers to four decimal places as needed. Part 1 out of 6 Find the mean The mean il ESSENEN IN
Answer:
Mean = 0.45
Standard deviation = 0.04035
Step-by-step explanation:
This is actually a very simple problem.
The question gives us the report that 45% of the teenagers in the age bracket own smartphones.
P = mean = 45%
Therefore the mean is 0.45.
I will go ahead to help you calculate the standard deviation.
√p(1-p)/n
n = 152
P = 0.45
√0.45(1-0.45)/152
= √0.45(0.55)/152
= √0.2475/152
= √ 0.001628
